GRATE.

SPECIFICATION forming part of Letters Patent No. 288,864, dated November20, 1883.

Application filed November Q8, 1881. (No model.)

To all whom it may concern: Y

Be it known that I, THoMAs Bossen, a citizen of the United States.residing at Bellaire, in the county of Belmont and State of Ohio, haveinvented certain new and useful Improvements in Grates and GrateStoves;and I do hereby declare that the following is a full, clear, and exactdescription of theinvention, which will enable others skilled in the artto which it appertains to make and use the same.

My invention relates to improvements in gra-tes for use in fire-places,open-front stoves, and other similar heating devices, and isparticularly adapted to such heating devices above specified as areprovided with a rack and side tile lining.

It consists in a vibrating grate composed of horizontal and transversebars firmly secured together and supported on aframe of peculiar form,the said frame having its ends and rear parts arranged to support thetiles which line the fireplace.

It consists, further, in the construction, combination, and arrangementof the several parts hereinafter fully described, and pointed out in theclaim.

In the drawings, forming apart of this application, I have shownmyimprovements applied to an open-front stove, for the reason that insuch application the invention can be more conveniently'illustrated anddescribed than if applied to an ordinary fireplace formed in a`chimnevbreast. 4

In the said drawings, Figure l is a front elevation of an open-frontstove having a part of the front grating brokenv away to show the edgeof the grate and a portion of the supporting-frame. Fig. 2 is a verticalsection on line a* fr, Fig. l, showing the grate and supportingframe incrosssection. Fig. 3 is a crosssection on line y y, Fig. l, showing aplan of the grate with its longitudinal bars eX- tended under the tiles.Fig. 4 is a vertical section on line a: x, Fig. 2, showing the grate andframe in longitudinal sec-tion and their relative positions to thetiles. Fig. isaplan of the grate and supporting-frame removed from thefireplace. Fig. 6 is a detail plan Fig. 7 is a detail plan view of thevibrating grate, and Fig. S is a cross-section of the supporting-frame.

The supporting-frame B is made to fit snugly between the end plates ofthe casing G and bar of the lire-place front A. Its end bars, B3, reston projections or supports G ou the end plates of the casing. The frameis open at its front side, the opening being closed by the bottom bar ofthe front. The small portions B2 are turned inwardly, as shown.Crossbars B5 connect the inner ends of theportions B2 and the.f rearbar, Bi. These cross-,bars have their upper edges cut down, so as tbdepress their upper surface below the upper surface of frame B. Thedepression is equal to the vertical thickness of the longitudinal barsof the grate, so that the upper 'faces of said bars, when placed on thecross-bars B5, will be iiush with the top of the said frame.

The vibrating grate B is composed of the longitudinal bars c and thetransverse rakers or bars c. The rakers a. being placed on top of thebars a., extend above the plane of the top of the frame B. Their endstherefore extend upward close to the side of the rear tile, E. Thesetransverse rakers extend up into the body of re or ashes in thefire-place, and when moved rake the said ashes down into the ashboX. Bythe position of their ends in close proximitj,r to the rear tile, theypreserve the grate steadily in place in the vibrating movements thereof.One of the longitudinal bars of the grate is provided with a perforatedlug, ai, extended downward, the opening therein being arranged oppositea suitable opening in the lower bar of the fire-front. The 'opening inthe lug cl receives the end of the shaker by which the grate isvibrated. One or more of the longitudinal bars a is providedA at itsopposite ends with stops ai', so arranged that they will come in contactwith the cross-barsv B5 and prevent the grate from be'- ing thrown toofar endwise. rIhe tiles which line the back and ends of the fire-placerest on the back bar and end bars of the frame B, covering andpreventing the fire from coming in contact with the latter. The' endtile E rests on the rear bar, Bi, and the end tiles E rest on the endbars, B.

The frame B, it will be seen, is almost entirely protected from beingburned by the great heat of the fire. The only portions er; posed arethe cross-bars B and smallportions between the back plate thereof andthelower of the ends of the parts B2; but these exposed parts are near theedges, or have an air-space between them and the re, so that there isvery little liability of being injured. The grate may be slipped endwisetill one of the stops a strike the cross-bar B5. This will bringl theopposite end of the grate flush with the inner face of the tile E', andthis end can then be lifted upward` and the grate taken out of thestove. It will be seen that thus the old grate may be easily removed anda new one as easily put in. The ends of the bars a eX- tend under thetiles E', and it is impossible Vfor the grate to get clogged by stone orother hard substances often found in coal.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The combination, with the frame B, having cross-bars B5, depressed belowthe upper sur- 2o THOMAS ROSSER.
